When not being snarky, this is the right take. The "Lizzy line" is a good thing and makes the case for infrastructure spend elsewhere. Although the snark is understandable in such a capital-city-centred country.

Of course, in living memory Universities were publicly funded rather than via student fees and many countries still have that model.

I'm trying to wean myself off use of "AI" - what these models are is general functional learners optimised for prediction, and the explainable bit is trying to get a lower dimensional representation of the learned functional behaviour. So, not as snappy, but it avoids the implications of >

Goodness there's arguments I really don't want to have online, but it's incredibly important to be clear that the Catholic civil rights movement in NI in the 1960s wasn't paramilitary.

I came to prefer "immunity gap" but yes, it's just a fact that infection rather than vaccination is what provides some of the immunity that keeps current numbers of infections relatively low.

There's always the issue though that the data need some adjustment - you can't get away from modelling that! But, one can try to use simpler models that make fewer assumptions. In a way there was more focus on doubling and having times because they delivered what policy needed at any time.

I can't claim to understand that either - except that for quite good reasons the ONS wants its outputs to be very tightly quality controlled and to leave higher uncertainty analysis to researchers.

Real-time modelling of the SARS-CoV-2 pandemic in England 2020–2023: a challenging data integration Abstract. A central pillar of the UK’s response to the SARS-CoV-2 pandemic was the provision of up-to-the moment nowcasts and short-term projections to mon

Here's one I had a minor involvement in - although with more focus on hospitalisation (Fig 3) than death. I think their real-time model is basically consistent with the whole pandemic but doesn't focus on one specific outcome.

I think many research papers aim for IFR by age, i.e. something more complex. It's implicitly there in e.g. the public Cambridge modelling that calibrates carefully to death data and ONS community infection.

People tend to write wrappers for the really good Fortran implementations of classic algorithms like L-BFGS-B widely used now in machine learning rather than reimplement - sometimes there's just almost no room for improvement.

Palestine Action protesters arrested by police at London demo The Metropolitan Police said the number of arrests was the largest made by the force on a single day in the last decade.

When I expressed free-speech doubts about the UK's 2000 Terrorism Act, people often said, "Of course it isn't going to impact on peaceful protest". Now people often say, "What do the peaceful protesters expect, they're breaking an established law?"

Actually sort of this - these tools are models of language, why should they be able to do maths or count letters?

PS, in the same way you shouldn't buy stock prices on the basis of an epidemic model, you shouldn't take medical advice from a language model. Remember, LLM. It's in the name.
